Can CO2 / greenhouse gas levels override the effects of milankovich cycles?

I understand that we are, in all likelihood, towards the end of an interglacial period (the holocene). What I'd like to know is, what has a stronger effect on global temperatures - the low point of ...

Every 202,500 years, Earth wanders in a new direction; does it affect climate?

I refer to this article on nytimes.com: Every 202,500 Years, Earth Wanders in a New Direction TLDR: Scientists believe the earth's orbit oscillates between circular and more elliptical due to the ...

Does general relativity influence climate (vs Newtonian mechanics)

That may sounds like a silly question but here it is. One of the early great successes of general relativity was to explain the discrepancy between the prehilion advance of Mercury predicted by ...

Is 2,000 years from now a credible figure for return to glaciation?

I read this article, https://www.technologyreview.com/s/416786/global-warming-vs-the-next-ice-age/ "In about 300 years, all available fossil fuels may well have been consumed.Over the following ...

What are the relative contributions of planets to the Milankovitch Cycles?

When reading about the Milankovitch cycles here, it says: If the Earth were the only planet orbiting our Sun, the eccentricity of its orbit would not perceptibly vary even over a period of a ...

What does the precessional parameter measure?

I am wondering what is measured in the plots of change of precession, e.g. when describing Milankovitch Cycles. The values typically vary between .06 and −.06. I am also wondering about what the ...

Altering the Milankovitch Cycles [closed]

As I understand it, the Pleistocene ice ages were dictated by three major factors suggested by the Serbian geophysicist Milutin Milankovitch--eccentricity (orbital shape), obliquity (axial tilt) and ...

Are ice-ages dependent on an un-equal distribution of land-masses?

Having read this answer about the precession of the equinoxes and how it affects Earth's climate, my understanding was that only because of the differing affect of continental and maritime insolation ...

Carbon Dioxide levels appear to be linked to the Milankovitch cycles according to Ice Core data but what is the mechanism?

As in ice core data shows that $CO_2 $ levels have fluctuated on levels correlating to the temperature and ice levels, but I couldn't think of a mechanism for what might be the link between the ...

How does the precession of the Earth's apses affect climate?

The gravitational influence of the gas giants (plus general-relativistic effects) are known to cause the apses of the Earth's orbit to precess. For an illustration of that process, see this image. Now,...

Why are some theories as to the cause of glacation less popular among the scientific community?

There are a few theories as to the causes of glaciation. There's the Milankovitch Theory, which says that there are cyclical changes in Earth's orbit and in the tilt of Earth's axis that occur over ...
